hi, there is no backlight on my led screen, I replaced screen but it`s the same. I can`t find diagram for this laptop and can`t identify component marked with 303. I think is a fuse but not sure. Some one help?
Thanks.
I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.
On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.

Do Hisense tvs turn off by itself if the backlights are unplugged or are bad? Or is this a mainboard issue?

During another reassembly, I made a mistake, and...
Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!
My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.
This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...
